Ok, but that's one heck of a rip off if you ask me. A decent ISP will
give you a dynamic publicly accessible IP for free, and charge you
extra for your own public static address. For an ISP to be doing NAT
on it's network for it's customers, and be charging to give them a
public IP which I'm guessing is still dynamic, is a rip off.

Anyway, you have 3 machines you said with internet
connections. However, you still have one public IP address, unless you
purchased a block of static addresses. So, my point still stands, your
modem or router is still doing IP masquerading for you, and assigning
an internal IP to each of your 3 machines.
